When the second winding shaft 6 is in the winding working position, the third rotating mechanism 45 drives the second winding shaft 6 to wind through the second transmission assembly 61, the rim charge sequentially winds around the first transition roller 11, the guide wheel 34 and the second transition roller 12 and then winds around the paper cylinder core arranged on the second winding shaft 6, after the second winding shaft 6 is wound, the sliding table 32 moves to the central position of the second winding shaft 6, and the support 33 moves in a small-distance reciprocating horizontal manner to drive the guide wheel 34 to move in a small-distance reciprocating horizontal manner.

When the reel is replaced, the first rotating mechanism 43 drives the main shaft 42 to rotate 180 degrees, the main shaft 42 drives the turntable 41 to rotate, as shown in fig. 2, the first winding shaft 5 is in a winding working position, and the second winding shaft 6 is in a unreeling working position; then, the film breaking mechanism 2 cuts off the rim charge which spans between the first rolling shaft 5 and the second rolling shaft 6, and guides the rim charge to automatically wind on the paper cylinder core of the first rolling shaft 5, and simultaneously, the guide wheel 34 guides the rim charge to reciprocate for a small distance, so that the rim charge uniformly winds on the middle part of the paper cylinder core, and the rim charge is prevented from knotting during reel changing; the film breaking mechanism 2 resets, after the rim charge winds the middle part of the paper tube core for a period of time, the first translation mechanism 31 drives the guide wheel 34 to do reciprocating translation motion, so that the rim charge uniformly winds the paper tube core, and at the moment, coil materials on the second winding shaft 6 can be unreeled and a new paper tube core can be replaced to wait for the next winding.

When the rim charge passes through the second transition roller 12, the static eliminator 8 blows out positive and negative ions so as to eliminate static on the rim charge, thereby avoiding the coiled material after coiling, and the static is excessive so as to lead a human body to get an electric shock.

In a preferred embodiment, referring to fig. 3 and 4, the first translation mechanism 31 includes a mounting seat 311 provided on the frame 1, a fourth driving motor 312 provided on the mounting seat 311, a screw rod 313 rotatably connected with the mounting seat 311, a guide rod 314 provided on the mounting seat 311, and a connecting shaft 315 provided on the mounting seat 311, an output shaft of the fourth driving motor 312 is connected with one end of the screw rod 313, a screw nut meshed with the screw rod 313 is provided in the sliding table 32, two rollers 316 respectively slidingly connected with the guide rod 314 are provided on the sliding table 32, and the two rollers 316 are respectively slidingly connected with the top and the bottom of the guide rod 314 to avoid the sliding table 32 from overturning during the translation process; the fourth driving motor 312 drives the lead screw 313 to rotate in the forward and reverse directions, the lead screw 313 is meshed with the lead screw nut, and the sliding table 32 makes reciprocating translational motion along the guide rod 314 under the action of the guide rod 314.

In order to realize the reciprocating translational motion of the sliding table 32 in a certain stroke, referring to fig. 4, two stoppers 317 are provided on the connecting shaft 315, a travel switch 318 is provided at the bottom of the sliding table 32, specifically, the stoppers 317 are slidably provided on the connecting shaft 315, and the positions of the stoppers 317 can be locked by screws. The positions of the two stoppers 317 are adjusted according to the winding range of the rim charge, i.e. the length of the paper cylinder core. The first translation mechanism 31 drives the sliding table 32 to move to the left, when the stop 317 on the left triggers the travel switch 318, the sliding table 32 moves and turns, the first translation mechanism 31 drives the sliding table 323 to move to the right, and when the stop 317 on the right triggers the travel switch 318, the sliding table 32 moves and turns again, so that the reciprocating movement of the sliding table 32 is realized.

It should be noted that, in the prior art, when the guide wheel 34 continues to drive the rim charge to reciprocate for a long distance, the movement range of the rim charge is too large, so that the situation that the rim charge is knotted easily occurs, or the guide wheel 4 is in a static state, the rim charge is guided to be conveyed in a directional manner, so that the rim charge is only wound at a certain position of the paper tube core, the thickness of the rim charge wound at the position is large, the subsequent winding work is not facilitated, and the winding quality of the rim charge is poor. Therefore, compared with the prior art, the guide wheel 34 can be driven to reciprocate by a small distance by the rodless cylinder 35, the rim charge can be prevented from being knotted during reel change, and the winding quality is ensured.
